Despite a chorus of largely uncritical reporting, there is a growing contingent of those who question VW’s claim that their new MQB modular architecture will bring about significant savings. The latest among them is Bernstein Research. A report by noted analyst Max Warburton (who recently authored the definitive study on Chinese cars) questions VW’s claims and shows how MQB may be helpful, but not nearly as significant as VW claims. On the other hand, it’s worth noting that these reports are meant for end-user investors, not necessarily industry types.
